Abstract
We compared daily energy expenditure and body mass changes of captive yearling black brant (Branta bernicla nigricans) with and without backpack-mounted radio transmitters in a repeated measures design. Daily energy expenditure was estimated by continuously monitoring O2 consumption and CO2 production for 24 hours. Carrying transmitters had no effect on daily energy expenditure (P > 0.10) or mass loss (P > 0.3). We detected no temporal variation in daily energy expenditure after attachment of transmitters, an indication that any acclimation occurred within the first 24 hours. Because experimental birds were confined to a small (45 .times. 60 .times. 74 cm) chamber during metabolism measurements, our results do not address the influence of transmitters on the cost of locomotion.This publication has 4 references indexed in Scilit:
